Apparently, some ISPs block `githubusercontent.com` but not
`github.com`, so offer a mirror for the prelude & masterlists.

     <p>If you're on Windows 7, this may be because on the 22nd of February 2018, GitHub disabled support for connections using a version of TLS older than 1.2, and Windows 7 doesn't support TLS 1.2 by default. Windows 7 users must ensure they have the latest Windows updates, and that they have <a href="https://support.microsoft.com/en-us/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-a-default-secure-protocols-in">enabled TLS 1.2 support</a>.</p>
 
-    <p>If LOOT still can't update its masterlist, it's likely due to connectivity issues that are beyond our control. You can update it manually by downloading <a href="https://raw.githubusercontent.com/loot/prelude/v0.18/prelude.yaml">this file</a>, selecting "Open LOOT Data Folder" within LOOT's File menu and placing <code>prelude.yaml</code> in the <code>prelude</code> folder. Then, download the masterlist for your game from <a href="https://raw.githubusercontent.com/loot/game/v0.18/masterlist.yaml">this location</a> and place it in <code>games\&lt;game folder&gt;\</code>. Depending on your game, replace <code>game</code> within the URL with <code>morrowind</code>, <code>oblivion</code>, <code>skyrim</code>, <code>skyrimse</code>, <code>skyrimvr</code>, <code>fallout3</code>, <code>falloutnv</code>, <code>fallout4</code>, <code>fallout4vr</code> or <code>enderal</code>, and <code>&lt;game folder&gt;</code> within the folder path with <code>Morrowind</code>, <code>Oblivion</code>, <code>Skyrim</code>, <code>Skyrim Special Edition</code>, <code>Skyrim VR</code>, <code>Fallout3</code>, <code>FalloutNV</code>, <code>Fallout4</code>, <code>Fallout4VR</code>, <code>Nehrim</code>, <code>Enderal</code> or <code>Enderal Special Edition</code>. Note that Oblivion and Nehrim share the <code>oblivion</code> masterlist and Enderal and Enderal Special Edition share the <code>enderal</code> masterlist. Also note that you'll want to disable the "Update masterlist before sorting" option in LOOT's settings until your connectivity issues have been resolved.</p>
